Abstract

This paper is concerned with the boundary layer flow of steady incompressible and viscoelastic fluid (MHD) passing over horizontal porous circular cylinder. The effect of magnetic field that acts on the fluid is applied and the fluid is assumed to be flowing in a porous medium. Governing equations are built from the physical phenomena, i.e., from the continuity equation, the momentum equation and the energy equation. These dimensional governing equations are further reduced by using boundary layer theory and they are converted into non-dimensional form by substituting non-dimensional variables. Further, these non-dimensional equations are transformed into similar equations and then are solved numerically by using finite difference method. Computational results for the flow quantities are presented graphically. We obtain that the temperature profiles increase when both of mixed convection and magnetic parameters increase. The velocity profiles increase when both of mixed convection and magnetic parameters increase.
